Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
536,363,636,382/900,000,000,002
- The integer number above the bar is called numerator: 536,363,636,382
- The integer number below the bar is called denominator: 900,000,000,002
- The fraction bar means that the numerator is divided by the denominator.
- To get the fraction's value divide the numerator by the denominator:
The value = 536,363,636,382 ÷ 900,000,000,002
To reduce a fraction to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF
To calculate the greatest common factor, GCF:
- 1. Factor the numerator and the denominator (into prime factors), build their prime factorizations.
- 2. Multiply all their common prime factors, taken by the lowest exponents.
1. Factor the numerator and the denominator:
To factor a number (into prime factors) - or, in other words, to break it down to prime factors - or, in other words, to build its prime factorization: find the prime numbers that multiply together to get that number.
The prime factorizations:
Written with exponents:
536,363,636,382 = 2 × 3 × 3 × 3 × 7 × 2,659 × 533,641 = 2 × 33 × 7 × 2,659 × 533,641
536,363,636,382 is a composite number.
900,000,000,002 = 2 × 83 × 5,421,686,747
900,000,000,002 is a composite number.
536,363,636,382/900,000,000,002 =
(536,363,636,382 ÷ 2) / (900,000,000,002 ÷ 2) =
268,181,818,191/450,000,000,001
Yet another method to reduce the fraction
To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
536,363,636,382/900,000,000,002 =
(2 × 33 × 7 × 2,659 × 533,641)/(2 × 83 × 5,421,686,747) =
((2 × 33 × 7 × 2,659 × 533,641) ÷ 2) / ((2 × 83 × 5,421,686,747) ÷ 2) =
(33 × 7 × 2,659 × 533,641)/(83 × 5,421,686,747) =
268,181,818,191/450,000,000,001
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
268,181,818,191/450,000,000,001 =
268,181,818,191 ÷ 450,000,000,001 =
0.595959595979 ≈
